I agree with the above posts. The Swiss+Tech tools are much better than their SeberTech counterparts. They may look funny, but they work very well. I have a couple of the Micro-Pro XLs and a couple of the Micro-Plus 8-in-1s and they all work very well. If you either get one of these, try to get a stainless steel version. I like them mainly because opening the pliers will release it from your keychain to use separately.
The Squirt P4 would also be a good choice. It is very well-built but still very small. I have a couple of these as well as a couple of the S4s and they have all worked very well. As gatch mentioned above, the Leatherman Squirt EL from RadioShack is a good little tool. I have a couple of these and use them at work all the time stripping wires. It even has small needle-nose pliers on the very end. It has proved to be invaluable. At $40 the price may be a little high but I've seen several of them sell on Ebay for less.
Also, the SOG CrossGrip. I have a couple of these also and the compound leverage is awesome. It is very easy to use the pliers as it is just like a fluid motion. Sometimes, I just like to sit and play with it as the gears for the compound leverage are addictive. SOG also has the CrossCut to complement this tool. I also have a couple CrossCuts and the compound leverage works equally well on it.
No one has mentioned Gerber's new Clutch keychain tool. It is very inexpensive and seems to work very well. I have a couple of these as well as a couple of the Shortcuts. These are equivalent to the Squirt P4 and S4 that Leatherman has. But, I don't think they are anywhere near the quality of the Squirts, especially the other tools in the handle. However, the Clutch and Shortcut cost about half the price of a P4 or S4.
I know I have listed a lot of small tools as well as some that don't really apply to what you are wanting (i.e. scissors-based). But, I like to carry these small tools in pairs. In Leatherman's case, triplets. Below is how I have them arranged. I always carry a pliers-based tool as well as a scissors-based tool.
Swiss+Tech
Micro-Plus 8-in-1 (accompanied by my
Leatherman Micra on my keychain).
Leatherman
Squirt P4,
Squirt S4,
Squirt EL (pouches available to purchase from Leatherman or an authorized vendor).
SOG
CrossGrip,
CrossCut (each comes with their own pouch).
Gerber
Clutch,
Shortcut (no pouch).
Now, if only Leatherman would make a pliers-based Micra.
